The present disclosure generally relates to the art of sound transmitters, and more particularly, to an earpiece including a mechanically adjustable front vent.
In recent years, portable audio playback apparatuses have widely proliferated. The audio playback apparatuses output audio from earphones, for example, and thereby provide the sound to users. For the earphones, various types are available and the taste of earphones often varies from user to user. As an example of the earphones, numbers of earphones, called sealing, in-ear canal type, are commercialized in which an earpiece is attached to a front end of a sound conduit.
A related earpiece generally includes a main housing, a front housing engaged with the main housing for forming a volume, a sound generator accommodated in the volume, and an ear gel attached to a front end of the front housing for inserting into an ear of the user. The sealed in-ear canal earpiece prevents the ambient sound into the ear canal of the user.
Sealed in-ear canal headphones are able to produce significant bass response while also isolating the listener from external sounds through the use of sealing ear gel. However, the sealing nature of in-ear canal headphones can also cause unwanted conditions like the “occlusion effect” which means internally generated sounds like breathing are artificially amplified, or “microphonics” which means noise is generates from objects rubbing against the cable or other headphone structures. Besides, the user might want to allow ambient sounds to enter so as to be alerted to outdoor hazards such as honking car horns or barking dogs when running.
So, it is necessary to provide a new earpiece for solving the problems mentioned above.
Many aspects of the embodiment can be better understood with reference to the following drawings. The components in the drawings are not necessarily drawn to scale, the emphasis instead being placed upon clearly illustrating the principles of the present disclosure. Moreover, in the drawings, like reference numerals designate corresponding parts throughout the several views.
While the invention is susceptible of embodiments in many different forms, there is shown in the drawings and will herein be described in detail embodiment of the invention with the understanding that the present disclosure is to be considered as an exemplification of the principles of the invention and is not intended to limit the broad aspect of the invention to the embodiment illustrated.
Referring to
The main housing 11 includes a back cover 111, a sleeve 112 integrally molded with the back cover 11 and enclosing the bass tube 2. A ring-shaped slot 114 is formed in the back cover 111. The front housing 12 includes a front cover 121, a sound output tube 122 extending slantingly forwards from the front cover 121. And the ear gel 14 is assembled to one end of the sound output tube 122.
The housing 1 includes a plurality of sound holes. In this embodiment, the sound holes comprise a plurality of first sound holes 113 in the rear end of the housing 1, and a second sound hole 123 in the front end of the housing 1. The housing 1 further includes a plurality of mechanically adjustable front vents 124 in the front end of the housing 1. The amount and shape of the sound holes and the front vents 124 may be adjusted or changed according to the requirements of design, manufacturing, or individual user.
The first sound hole 113 is formed in the back cover 111 of the main housing 11 used for communicating the volume 10 with the outside from the back end of the housing 1. The second sound hole 123 is formed in the sound output tube 122 for transmitting the sound produced by the sound generator 3 to the user's ear. The front vent 124 is formed in the front cover 121 of the front housing 12 for communicating the volume 10 with the outside from the front end of the housing 1 so as to allowing ambient sounds to enter.
Referring to
The front housing 12 further includes a post 125 protruding from the center of an inner face of the front cover 121 and passing through the hole 520 of the rotor 52. The post 125 is serving as an axis of rotation of the rotor 52. The vent cover 522 is disposed on the inner face of the front cover 121 and capable of rotating about the post 125. The connecting portion 523 is disposed in a space formed between the sound generator 3 and a side wall of the housing 1 and capable of moving in the space. The ring 51 is received in a ring-shaped slot 114 of the main housing 11 and capable of moving along the slot 114 by pushing the lever 511.
The front vent 124 is disposed within a projection of the rotating region of the vent cover 522 onto the front cover 121. Therefore, when the rotor 52 is actuated to rotate about the post 125 by pushing the ring 51, the vent cover 522 is moved to close or open the front vents 124 on the front cover 121. The amount of the open front vents 124 which is communicating with the volume 10 is mechanically altered by the adjustment module 5. In the embodiment, there are three front vents 124, and make one, two or all of the three front vents 124 open or close is easy to come true by moving the ring 5.
The present disclosure allows the user to control the amount of ambient sound that is admitted into the ear canal by control the amount of the open front vents 124 with the adjusting module 5. While using the headphones when running, the user could leave one or more front vents 124 open to allow the ambient sounds to enter so as to be alerted to outdoor hazards such as honking car horns or barking dogs. On the other hand, when watching a movie on an overseas flight, the user could close all the front vents 124 to have as much noise isolation as possible. Besides, the amount of the open front vents 124 also determines the perceived bass response of the headphone. It allows the user to vary the amount of apparent low frequency response the headset delivers.
While the present invention has been described with reference to a specific embodiment, the description of the invention is illustrative and is not to be construed as limiting the invention. Various of modifications to the present invention can be made to the exemplary embodiment by those skilled in the art without departing from the true spirit and scope of the invention as defined by the appended claims.
